Pregnane- and pregn-5-ene glycosides – mixture known as condurangin (including condurango glycosides A, A0, Al, BO, C, CI, DO, E0, E2); Flavonoids (including trifoliin, hyperoside, quercitrin, rutin, and saponarin), Caffeic acid derivatives (including chlorogenic acid, neo-chlorogenic acid) and essential oils. (PDR, pg. 217)
The medicinal part is the dried bark of the branches and trunks.
Alterative, circulatory stimulant, stomach relaxant, bitter, adaptogenic, orexigenic, diuretic, tonic, antiseptic, heart stimulant, anti-syphilitic, anti-cancerous, and nervine. (Shook, pg. 349-350)
Condurango stimulates the secretion of saliva and gastric juices. It is used for nervous indigestion, anorexia nervosa, neoplasm of the stomach and intestines. It calms pain in stomach disorders following gastric ulcer and lessens vomiting (Le Monde Medical Journal). Traditionally condurango is used for loss of appetite, atonia of the stomach, painful nutritional disorders, for stomach cancer to alleviate nausea, as an appetite stimulant and to increase tolerance of food. (PDR, pg. 217)
Condurango has found its chief use as a cancer remedy, especially those originating in epithelial structures, epithelioma, etc. (John Clarke MD).
It is used by native Indians to cure many cases of syphilis and cancer. (Shook, pg. 349-350) Condurango is also used to allay the pain in gastralgia accompanying cancer of the stomach, stricture of the oesophagus with burning pains behind the sternum, vomiting of food, and indurations, chronic gastric catarrh, epithelioma of lips or anus, ulcerative stage of carcinoma cutis when fissures form, varicose ulcers, tumours, and lupus. (Boericke, 1993)
In Homeopathic medicine, condurango is used for cracked skin and constriction of the alimentary canal.
Condurango is also approved by Commission E for (1) Dyspeptic complaints and (2) Loss of appetite.
Dr. Sebi tells us that condurango is good for the blood and noted that he used it to cure a woman of leukemia. (theafricanbiomineralbalance.com, 2019)
‘Condurango contains an abundance of nascent oxygen, which we know is the greatest antiseptic in the world, and is, therefore, indicated in shortness of breath, dyspnoea, dyspepsia, dyscratic conditions, pus-forming diseases, and in failure of the heart, lungs and kidneys to perform their proper functions.’ (Shook, pg 350)
Preparations – Thrice daily.
Liquid Extract: Dose – 2-4ml (30-60 drops) in water. (Bartram, 1995)
Tea 1: 1-4g to cup boiling water. Half-1 cup. (Bartram, 1995)

– Its effective use as a digestive agent was proven in the 1980s, when researchers reported that the herb increased the amount of various digestive enzymes and digestive fluids in the stomach.
– Research published in J Pharmacopuncture. Sep 2013 indicated that it exhibited antitumoral effect in animals.
– Research published in Pharmacogn Mag. May 2015 noted findings indicating ‘its potential as a strong candidate for anti-cancer drug formulation’.
– Research published in J Pharmacopuncture. 2014 Jun;17(2):7-17 concluded that the ‘anticancer efficacy of an ethanolic extract of Condurango for treating BaP-induced lung cancer in rats lends support for its use in various traditional systems of medicine.’
